As above my TJ's throttle pedal is sticky when I first push from 0% to 5% pressure then after that it is free to move as normal.
Any ideas as to what it could be?
Thanks

Mine has done this for ages, feels like you are hitting a switch and you have to push through the resistance, painful thing is it isn't there all the time
So, as above, any ideas, solutions
3rd person with the same issue. My ex mechanic says change the throttle cable, which he says is a $30 5 minute DIY job, so when I get a chance I'll give it a crack.

Wrong, wrong, wrong!
No new cable, 1 minute fix tops.
Simple cause for this. There is a "stop" screw on the throttle body, which stops the butterfly from closing fully and jamming or locking in the closed position. As wear accumulates on the butterfly shaft, the jamming starts to occur.
Find the screw, and give it an eight of a turn in, fixes the problem.
How do I know this? lol
My first Magna, a TP, had this problem, and that screw was missing altogether. Since then, I've checked any "new" car with a throttle body on it I buy for that binding, and most of them were doing it to some extent. Seems to not happen until you get near the 200,000 km though.
DISCLAIMER: Of course, I could be wrong. Your throttle cable may be full of rust and mud because you drove through really deep water, your throttle pedal may be rusty where the pedal meets the lever, or the pivot under the dash could be dirty and rusty, or the lever could be bent. Or you need to see an orthopedic surgeon because you have a problem with your right ankle.
BUT I'd start by looking at that stop screw . . . . try simple solutions first. lol
These are third gens, not first gens. The butterfly closes fully and uses a bypass gallery for idle. Possible causes are sticky cable, dirty throttle body, or sticky return spring.

Wrong Wrong Wrong, DONT TOUCH THE TRROTTLE STOP SCREW unless you know what you are doing, these are factory preset
99% of the time is a dirty throttle body, a simple spray through generally wont fix, you need to take it off and give BOTH sides of the throttle plate a clean, not just the outside. Get yourself some of the Subaru Throttle Body Cleaning Foam (like the Subaru stuff) and use that, is magic and will clean that bugger up like new.
With TCL you will have no throttle, generally will not feel the stiff pedal, with non TCL will fell like someone has welded the cable and all of a sudden lets go

Agreed with the above - with any form of troubleshooting, perform the most simple solutions first as it can save time and headaches down the line.

I had the same issue when I first got my car, it was the biggest pain in the ass in traffic. I ended up squirting the outside of the throttle body and cable with a fair amount of WD40 few months back and it got rid of the problem.

lol An interesting rage of responses!
Can the people with this problem get back and let the rest of us know what the problem was, and how they fixed it?

I will try the above recommendations, starting with the simple ones until it is fixed.

I had this problem straight after my 3.5 & manual conversion. Carby cleaner fixed it straight up.

I had this issue when the car sat for 3 weeks once. Went away after a bit of driving.
